  • Download the distribution you want to install and extract the filefolder into the $HOME directory by unpacking using the following commands [examples are shown for Linux  64 bit compilation]

    gunzip smc_linux_intel_64_v62.tar.gz [64bit]
    tar -xvf smc_linux_intel_64_v62.tar

    where v61 is the version number!
  • If you use csh or tcsh shell

    Add to the .cshrc file the folowing lines. This is only needed first time you installing the code!

    setenv SMC_DIR $HOME/simind/smc_dir/
    setenv PATH $HOME/simind:$PATH

    Execute the command

    source .cshrc

    to make the changes effective.
  • if you use bash shell

    Add in your .bash_profile


    export PATH
    export SMC_DIR


Included is a data file 'bench.smc'. To make a test simulation

/home/simind/> simind bench

    Installation: Windows

    • Create a directory c:\simind
    • Unpack smc_win_zz_v62.zip [where zz is either 32 bit version of 64 bit,  v62 is the version number] into a foler c:\simind! Keep the folder information while unzipping and be sure that a directory c:\simind\smc_dir with files of for example extension *.cr3 have been created.

    The Castor Binaries

    Here is a link to a zip file containing a distribution for the castor software version 1.0 with pre-build executables for Linux, MacOS and Windows (32 and 64-bit). This zip-file can be seen as a starting point to use the castor reconstruction. It is, however, strongly recommended that users of this program register themseft to the castor community list at the www.castor-project.org in order to receive information about future updates and to get other important information. On the page, there is also information about to configure and compile the builds to particular preferences since it is not the intention that this website should be regarded as a mirror-site.

    To get started and use the smc2castor program for reconstruction of simind-genereated SPECT projections then following installation/preparation is needed.

    • Download the zip file castor.zip from the web-page.
    • Extract the whole file structure to a convenient place on your harddrive.
    • Define the environmental variable CASTOR_CONFIG to the absolute path of the config folder within the castor directory structure.
    • Add the relevant bin folder to you PATH environmental variable (that is, either bin_osx, bin_linux, bin_win32 or bin_win64).
